In vitro bioaccessibility of copper, iron, zinc and antioxidant compounds of whole cashew apple juice and cashew apple fibre (Anacardium occidentale L.) following simulated gastro-intestinal digestion
Considering the lack of research studies about nutrients' bioaccessibility in cashew apple, in this study the whole cashew apple juice and the cashew apple fibre were submitted to simulated in vitro gastrointestinal digestion. The samples were analysed before and after digestion and had their copper, iron, zinc, ascorbic acid, total extractable phenols and total antioxidant […]
Almond hulls as a biofuels feedstock: Variations in carbohydrates by variety and location in California
Hulls of the almond (Prunus dulcis (Miller) D.A. Webb) have a high content of fermentable sugars (glucose, fructose, sucrose), and are a potential feedstock for biofuels and other uses. The state of California in the United States produces the majority of the world's almonds. Six almond varieties across seven counties in California were studied to […]
The use of NARX neural network for modeling of adsorption of zinc ions using activated almond shell as a potential biosorbent.
In this study, nonlinear autoregressive model processes with exogenous input (NARX) are applied for the prediction of percentage adsorption efficiency for the removal of zinc ions from wastewater by activated almond shell. The effect of operational parameters such as pH, dosage, particle size and initial metal ions concentration are studied to optimize the conditions for […]
Mechanical, barrier and morphological properties of pea starch and peanut protein isolate blend films
Mechanical, barrier and morphological properties of edible films based on blends of Pea starch (PS) and Peanut protein isolate (PPI) plasticized with glycerol (30%, w/w) were investigated. As PPI ratio in PS/PPI blends increased, the thickness of films decreased, the opacity slightly elevated and color intensified. The addition of PPI to the PS film significantly […]
Effects of fragmentation and particle size on the fuel properties of hazelnut shells
Fragmentation of biomass leading to the formation of very fine particles is a serious concern particularly in biomass burning systems because of their enormous thermal reactivity. Some types of biomass species have a considerable tendency to form such problematic dusts. For this purpose, the extent of size fragmentation during breaking, storage, and transportation was investigated […]
Valorization of date palm (Phoenix dactylifera) fruit processing by-products and wastes using bioprocess technology – Review
The date palm Phoenix dactylifera has played an important role in the day-to-day life of the people for the last 7000 years. Today worldwide production, utilization and industrialization of dates are continuously increasing since date fruits have earned great importance in human nutrition owing to their rich content of essential nutrients. Tons of date palm […]
Date palm by-products as a new ingredient for the meat industry: Application to a pork liver pâté
Date palm is an interesting source of bioactive compounds that could be used as ingredient in meat products; thus a campagne type pork liver pâté was elaborated using fresh date by-products (0, 5, 10 and 15%). Physicochemical properties, pigment and lipid oxidation, residual nitrite level, texture and sensory analysis during 4 days after the elaboration […]
A sustainable approach to controlling oil spills
As a result of the huge economic and environmental destruction from oil spills, studies have been directed at improving and deploying natural sorbents which are not only the least expensive but also the safest means of spill control. This research reviews the limitations and environmental impact of existing cleanup methods. It also justifies the need […]
Screening Natural Antioxidants in Peanut shell Using DPPH-HPLC-DAD-TOF/MS methods.
Peanutshell, a byproduct in oil production, is rich in naturalantioxidants. Here, a rapid and efficient method using DPPH-HPLC-DAD-TOF/MS was used for the first time to screen antioxidants in peanutshell. The method is based on the hypothesis that upon reaction with 1, 1-diphenyl-2-picrylhydrazyl (DPPH), the peak areas of compounds with potential antioxidant activities in the HPLC […]
Carcass performance and meat mineral content in Balouchi lamb fed pistachio by-products
This experiment investigated the effect of pistachio by-products (PB) in the feed of weaned Balouchi lambs on their daily gain, carcass traits and on the levels of Ca, Zn, Fe and Cu of Longissimus dorsi muscle. Twenty eight male lambs were divided into four groups with 7 lambs each and fed separately for 90 days. […]
